If you're battling strong abeam winds (more than 20-30 knots) in cruise, don't forget to factor into your thinking a significant drop in G/S if the direction is out by 10-20 degrees from what is forecast. A number of years ago I got very nervous when a planned G/S of 75 knots turned into 60 for the flight home. I had to lob into Tyabb due to losing so much time.
Enjoy it. Take lots of piccies.
